This is a visualization of some level surfaces of the equation G(x,y,z) = (4-x^2-y^2-z^2)*((x-c)^2+y^2). Another way to think of it is as the product of two distance fields, one from a sphere, and the other from a line, where the line’s distance from the center of the sphere is given by c. I don’t have an exact date for this, but it would have been sometime in the fall of 1988.
